Arcetri, 1928 -1932
Early in 1928, a short time after receiving my doctorate at the University of Bologna, I was offered a position of assistant at the Physics Institute of the University of Florence. The Institute rose among olive trees, on the hill of Arcetri, a short distance from the villa where Galileo had spent the last years of his life as a political exile. The chair of physics was held by Professor Antoni...
متن کاملSystem NEL is Undecidable
System NEL is a conservative extension of multiplicative exponential linear logic (extended by the rules mix and nullary mix) by a self-dual noncommutative connective called seq which has an intermediate position between the connectives par and times. In this paper, I will show that system NEL is undecidable by encoding two counter machines into NEL. Although the encoding is simple, the proof o...
متن کاملThe Undecidability of System NEL
System NEL is a conservative extension of multiplicative exponential linear logic (MELL) by a self-dual non-commutative connective called seq which lives between the par and the times. In this paper, I will show that system NEL is undecidable by encoding two counter machines into NEL. Although the encoding is quite simple, the proof of the faithfulness is a little intricate because there is no ...
متن کاملC1py00484k 1890..1898
End-functionalized polyethylene oxides containing cleavable acetal and clickable azide terminal groups (PEO-acetal-N3 and N3-acetal-PEO-acetal-N3) were obtained by the reaction between commercially available PEOs and 2-chloroethyl vinyl ether using pyridinium p-toluenesulfonate. This results in acetal-linkages which can be further functionalized by nucleophilic displacement with sodium azide. B...
متن کاملNEL, Morphine and Peritonitis in Chickens
BAKGROUND : Morphine exerts immunomodulatory effects dependent on several factors including species and parameter examined. The aim of this study was to assess the influence of morphine on experimental peritonitis and leukocyte activity in young chickens of both sexes. METHODS: Peritonitis was elicited by intraperitoneal injection of thioglycollate (TG) alone or supplemented with morphine; addi...
